FIGS. 1 and 2 are cross-sectional views showing an example of a brake operating state and a brake releasing state of a conventional brake release mechanism. 1 is a rotary plate attached to the rotating shaft of the motor M, 2 is a brake lining that is joined to and detached from the rotary plate 1, 3 is an armature to which the brake lining 2 is attached, and 4 is a rotary plate that allows the armature 3 to move freely in the suction direction. It is a pin that is fixed in the direction of rotation. 5 is a spring for pressing the brake lining 2 against the rotary plate 1; 6 is an electromagnet for attracting the armature 3; 7 is a shaft connected to the armature 3 at its center; 8 is the shaft 7.
This is a cam lever that is connected to the shaft 7 and has a cam for moving the shaft 7 in the axial direction. 9 is a spring for returning the shaft 7 to the neutral position, and 10 is a shim for adjusting the connection position between the shaft 7 and the armature 3. As shown in FIG. 1, when the cam lever 8 is located in the horizontal direction, that is, in the axial direction, the shaft 7 is adjusted so as not to be connected to the armature 3. Therefore, when the electromagnet 6 is not energized, the rotating plate 1 and the brake lining 2 are fixed by friction torque caused by the pressing force of the spring 5. When the electromagnet 6 is excited, the armature 3 is attracted to the electromagnet 6 against the pressing force of the spring 5, the brake lining 2 is separated from the rotating plate 1, and the rotating plate 1 rotates freely. On the other hand, when the electromagnet 6 is de-energized, the brake lining 2 is again pressed against the rotating plate 1 by the pressing force of the spring 5 and operates as a brake.
During this braking operation, when the cam lever 8 is tilted perpendicular to the axial direction as shown in FIG. The electromagnet 6 is moved in the direction ○a against the pressing force of the spring 5 to release the braking action.
上記のように構成した従来のブレーキ装置のブ
レーキ解放機構によれば以下に示すような欠点が
あつた。 The brake release mechanism of the conventional brake device constructed as described above has the following drawbacks.
(1) 軸方向にカムレバー8の回転するスペースが
必要となりブレーキ解放機構の全長が軸方向に
長くなる。(1) Space is required for the cam lever 8 to rotate in the axial direction, and the overall length of the brake release mechanism becomes longer in the axial direction.
(2) スプリング5の押付力が強くなると、カムレ
バー8の操作に多大な力が必要となり、操作に
困難が伴なう。(2) If the pressing force of the spring 5 becomes strong, a large amount of force is required to operate the cam lever 8, making the operation difficult.
(3) スプリング5に傾きがあると、ブレーキ解放
状態においてアーマチユア3も傾き、ブレーキ
ライニング2が回転板1から完全に離脱せずブ
レーキライニング2を損傷する恐れがある。(3) If the spring 5 is tilted, the armature 3 will also tilt when the brake is released, and the brake lining 2 will not be completely detached from the rotating plate 1, which may cause damage to the brake lining 2.

The present invention has been made to solve the above-mentioned drawbacks, and has a brake release mechanism that has a short overall length, is compact, is easy to operate, and can perform brake operations reliably without damaging the brake lining. In order to obtain a brake release mechanism that can be used, a plurality of brake release mechanisms are arranged in the circumferential direction of the rotary plate, and a lug provided on the shaft of the brake release mechanism is engaged with the peripheral edge of the armature of the brake device to perform the braking action. The present invention provides a brake release mechanism characterized by the following features.

Note that parts having the same functions as those in FIGS. 1 and 2 are given the same symbols, and explanations thereof will be omitted. 1
1 is a lug fixed to the shaft 7 with a screw and has an L-shaped cross section and engages with the peripheral edge of the armature 3; 12 is a housing that fixes the brake release mechanism in the circumferential direction of the rotating plate 1; A plurality of such brake release mechanisms are arranged in the circumferential direction of the rotary plate 1.

し付けられブレーキとして動作する。 The effects of the present invention configured as described above are as follows. As shown in Figure 3, the cam lever 8
is located in the axial direction, the lug 11 fixed to the shaft 7 is not engaged with the armature 3. Therefore, when the electromagnet 6 is not energized, the rotary plate 1 and the brake lining 2 are fixed by friction torque caused by the pressing force of the spring 5. When the electromagnet 6 is excited, the armature 3 is attracted to the electromagnet 6 against the pressing force of the spring 5, the brake lining 2 is separated from the rotating plate 1, and the rotating plate 1 rotates freely. On the other hand, when the electromagnet 6 is de-energized, the brake lining 2 is again pressed against the rotating plate 1 by the pressing force of the spring 5 and operates as a brake.

向○ロに移動させブレーキ作用を解放する。 When the cam lever 8 is tilted perpendicularly to the axial direction as shown in FIG. 5 during this braking operation, the lug 11 fixed to the shaft 7 moves in the direction of the electromagnet 6 and engages with the armature 3. The armature 3 is moved in the direction of the electromagnet 6 against the pressing force of the spring 5 to release the braking action.
以上の説明から明らかなように本発明によれば
次のような顕著な効果を挙げることができる。
As is clear from the above description, according to the present invention, the following remarkable effects can be achieved.
(1) 軸端に設けられたカムレバーの回転するスペ
ースが不要となり全長を短かくコンパクトにす
ることができる。(1) No space is required for the cam lever provided at the shaft end to rotate, making the overall length shorter and more compact.
(2) 回転板を片側ずつ移動できるため操作力が小
さくてすむ。(2) Since the rotating plate can be moved one side at a time, the operating force is small.
(3) 回転板の周縁部を複数のラグで移動させるた
め回転板が傾きにくく、ブレーキライニングが
回転板より完全に離脱し、引きづりによりブレ
ーキライニングを損傷することがなくブレーキ
動作も確実である。(3) Since the peripheral edge of the rotating plate is moved by multiple lugs, the rotating plate is unlikely to tilt, and the brake lining is completely detached from the rotating plate, ensuring reliable braking without damaging the brake lining due to dragging. .
